5 Claims.

This invention relates to looms and it has particular reference to aselvedge guard for damping the vibration of the warp threads on a loom.

The principal object of the invention is to provide a device adapted tobe adjustably and detachably mounted on the front warp support of a loomto overlie the selvedge portion of the warp to damp excess vibrationthereof which otherwise results in frictional wear on the underside ofthe sliding bar feeler holders and consequent breakage of the warpthread by reason of contact there of with the roughened undersurfaces ofthe said f eeler bar holders.

Another object of the invention is to provide a selvedge guard for loomsof highly simplified construction which is not only efiective tominimize breakage of the warp threads, as stated, but also eliminatesthe necessity of replacing the bars which have become worn and impairedby constant frictional wear imposed thereupon by the vibration of thewarp selvedge, all of which represents a loss in shut down time of theloom.

With the foregoing objects as paramount, the invention has particularreference to certain features of accomplishment, to become manifest asthe description proceeds, taken in connection with the accompanyingdrawing, wherein:

Figure 1 is a fragmentary perspective view of the warp stop mechanism ofa loom, showing the position of the invention thereon.

Figure 2 is a rear end elevational view of a selvedge guard constructedaccording to the invention, and

Figure 3 is a perspective view of the invention.

Continuing with a more detailed description of the drawing, reference isprimarily made to Figure 1 wherein numeral I denotes a stand or bracketsupported upon which is mounted the sliding feeler bar end support Hwhich latter supports the sliding feeler or detecting bars I! and fixedassociated detecting bars IS, the former being actuated longitudinallyby means of the fingers l4. Disposed above and parallel with the frontwarp support I is the assembly of sliding feeler bar holders l6 whichoverlie the warp threads II, the latter extending transversely acrossthe bar l5.

The foregoing mentions briefly the elements of a loom with which thepresent invention is directly associated and inasmuch as the type ofmechanism represented in the drawing is well known to those versed inthe art, it is considered that a detailed description thereof isunnecessary.

Accordingly, the invention consists of the device exemplified in Figures2 and 3 and which comprises a body constructed of metal or plastichaving relatively parallel legs I8, defining a saddle of substantiallyU-shape to conformably rest upon the front warp support l5. Integralwith and extending at right angles to the longitudinal axes of the legsI8 is a tongue Hi. This tongue is bent upwardly at its junction with thelegs at a in order that the plane of the tongue will be spaced slightlyabove the upper edge of the warp support 15, to define a space throughwhich the warp threads I! may pass.

The ends of the legs l8 are apertured to receive a bolt 20, on which isthreaded a nut 2|. In this manner the guard is firmly secured inposition on the warp support l5, as shown.

In the absence of means to prevent, the warp threads I1, duringoperation of the loom, bounce or vibrate at the selvedge to such degreethat they strike against the undersides of the feeler bar holders l6 atb. The continuous frictional wear thus imposed at these points on thebar holders results in a wearing away of the edges, causing them tobecome irregular and rough.

VVnile highly efiioient warp stop mechanisms have been devised to stopthe loom upon warp breakage to minimize damage, the roughened surfacesof the holders l6 increase to a considerable extent the breakage of thewarp threads and as a result, the shut down time for a loom isproportionately increased.

It is therefore the object and intent of the present invention, asdescribed, to reduce to a minimum or eliminate entirely the wear uponthe bar holders l6 which will obviate such breakage of the warp threadsthat would otherwise occur when contacting the bar holders, by limitingthe vibration of these threads through the medium of the tongue I9,against which the selvedge threads bear. It is obvious that the mannerin which the guard is mounted permits of ready adjustment thereof on thewarp support l5 relative to the selvedge and further, it is apparentthat a worn guard may be removed and replaced with a new guard withoutrequiring that the loom be stopped for the purpose.

legs adapted to straddle the front warp support of said loom, and aright angular extension integral with and elevated above the junction ofsaid legs and adapted to overlie the selvedge warp threads advancingover said warp support, to damp excess vibration thereof.

2. A selvedge guard for looms including a member having relativelyparallel legs mounted adjustably on the warp support of said loom and atongue originating at and extending at right angles from the junction ofsaid legs to overlie and damp excess vibration of the selvedge threadsof the warp moving over said warp support.

3. As a new article of manufacture, a selvedge guard for loomscomprising a member havin relatively parallel legs adjustably anddetachably connected to the warp support of said ioom and having meansoverlying the selvedge portion of the warp to damp excess vibrationthereof.

' 4. As a new article of manufacture, a selvedge guard for loomscomprising a member attached adjustably to a loom and having a tongueportion extending over and slightly above the selvedge of the warp tohold the same within predetermined limits in its vertical displacementupon the warp support of said loom.

5. As a new article of manufacture, a device for limiting verticalvibration of the warp selvedge of a loom comprisinga member attached tothe loom and provided with a tongue portion having a free end andoverlying said seivedge at a point spaced thereabove and means foradjustably securing said member to the loom.
